Effects of vitamin D supplementation on cardiac biomarkers: Results from the STURDY trial.
Article in American journal of preventive cardiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: In observational studies, older adults with low serum vitamin D levels are at higher risk of cardiovascular disease (CVD), but randomized trials have failed to demonstrate reduction in CVD risk from vitamin D supplementation, possibly because the doses of vitamin D supplements tested were too low. Our objective was to determine if higher doses of vitamin D supplementation reduce high-sensitivity cardiac troponin (hs-cTnI) and N-terminal pro-b-type natriuretic peptide (NT-proBNP), markers of subclinical CVD. Methods: The Study to Understand Fall Reduction and Vitamin D in You (STURDY) was a double-blind, randomized, response-adaptive trial that tested the effects of 4 doses of vitamin D3 supplementation (200, 1000, 2000, 4000 IU/day) on fall risk among older adults with low serum 25-hydroxyvitamin D concentrations (10-29 ng/mL). Hs-cTnI and NT-proBNP levels were measured at baseline, 3-, 12-, and 24-month follow-up visits. For this ancillary study, we used data from the original trial and compared participants by treatment group: low-dose (200 IU/day) or high-dose (1000+ IU/day). The effects of vitamin D dose on biomarkers were assessed via mixed effects tobit models. Results: Among 688 participants (mean age of 76.5) hs-cTnI increased in both the low- and high-dose groups by 5.2 % and 7.0 %, respectively; likewise, NT-proBNP increased by 11.3 % and 9.3 %, respectively. Compared to the low-dose, high-dose vitamin D supplementation did not affect hs-cTnI (1.6 %-difference; 95 % CI: -5.3, 8.9) or NT-proBNP (-1.8 %-difference; 95 % CI: -9.3, 6.3). Conclusions: Compared to low-dose vitamin D supplementation, doses ≥1,000 IU/ day did not affect markers of subclinical CVD in older adults with low serum vitamin D levels.
